### Question

The sum of three consecutive odd integer numbers is -2313. The middle among the three is?

**A**

-771.

**B**

-770.

**C**

-768.

**D**

-769.

**Soln.**

**Ans: a**

Let the numbers be 2n - 3, 2n - 1 and 2n + 1. The sum is 3(2n - 1) = 3 x middle. We are given 3 x middle = -2313, ⇒ middle = $-2313/3$, i.e., middle = -771.
